【 摘 要 】

The primary aim of the project was to increase cavitation performance of a big mixed-flow pump. The CFD software was used as a main research tool. The two kinds of numerical models were used to solve this problem - both were presented. The results were verified on the basis of comparison with experimental results obtained for real and model pumps. The interesting way of estimating cavitation performance was presented. The pump characteristics before and after the modernisation were shown.
